Iran’s ballistic missile tests are a concern, White House spokesman Josh Earnest said on Wednesday.
Speaking to reporters, he added that the United States government is looking into reports that Iran conducted yet another such test last month, in a breach of UN Security Council resolutions.
"The Iran ballistic missile program has been ... a source of concern for years ... and it continues to be," Earnest told reporters, according to Reuters. He added that the United States was deepening its cooperation with partners including Gulf Arab states to counter the program.
On Monday, officials told Fox News that Iran tested a ballistic missile on November 21, the second such test since signing the nuclear agreement with Western powers in July.
The American Ambassador to the UN, Samantha Power, on Tuesday said Washington was reviewing reports of the Iranian test, and hours later an American official confirmed the test took place and said other undeclared tests occurred earlier than that.
Shortly after Iran’s October missile test, Earnest said Iran likely violated UN sanctions, but stressed that the test would not affect the implementation of the deal reached with world powers.
Iran has rejected claims that the missile was capable of delivering a nuclear warhead and also rejected the idea that the missile test was against UN resolutions.
Nevertheless, the United States, Britain, France and Germany subsequently called for the United Nations Security Council's Iran sanctions committee to take action over the missile test.
So far, no action has been taken by the committee, though Power said on Tuesday council members would be discussing the issue next week.
